San Francisco 49ers cornerback Richard Sherman was placed on injured reserve Wednesday with an apparent leg issue.

However, 49ers head coach Kyle Shanahan suggested Sherman's absence will be brief.

Shanahan indicated the team is taking precaution after Sherman felt a little worse for wear on Monday, though the team expects him back on the field shortly:

“It happened like the last four plays of the game, I believe,” Shanahan said, via Mike Florio of Pro Football Talk. “We were still waiting to see how it felt on Monday and later Monday afternoon we found that it was hurting a little more than he expected. Fortunately, we were able to do the IR to return. So hopefully won’t be too long.”

Ian Rapoport of NFL Network reported Sherman suffered an apparent calf strain, though he also suggested the injury is not related to the ruptured Achilles Sherman sustained in November of 2017.

Sherman will still have to miss a minimum of three weeks, but the 49ers are hoping the minimum is all it will take for his calf to heal.

Arizona Cardinals quarterback Kyler Murray targeted Sherman four times on Sunday, completing three of those attempts for 22 yards.

The 2019 Offensive Rookie of the Year gave the 49ers fits with his scrambling and ability to make plays outside the pocket.

However, New York Jets quarterback Sam Darnold does not have the same kind of athleticism as Murray. San Francisco's secondary will hope its pass-rushers can wreak havoc against a fairly shallow Jets offensive line in Week 2 as they wait for Sherman to return at the outside corner spot.
